Triceps Pushup

Reps: 10

Place hands directly below shoulders, feet hip-width apart. Keeping elbows pointed back and as close to your sides as possible, slowly lower body to the ground. Once your chest touches the floor, press back up to a straight-arm plank. Be sure to keep core and legs engaged the entire time. If this is too challenging, modify by dropping down to your knees. Do 10 reps.

Side Plank with Dumbbell Raise

Reps: 10 per side

Grab a dumbbell with left hand and come into a side plank with right elbow directly below shoulder, feet stacked. Raise hips off the ground so that your body forms a straight line from ankles to shoulders. Extend left arm straight out directly above the shoulder, still holding the dumbbell. Lower left arm back down until it's parallel to the ground. Make sure to keep hips lifted and chest up the entire time. Do 10 lifts on each side, and then grab a jump rope for a quick cardio blast.

1-minute cardio blast: Jump rope as fast as possible for 1 minute, swinging the rope with your wrists rather than your arms.
